"The most important fix here adds a missing CPU model to the recent
Gather Data Sampling (GDS) mitigation list to ensure that mitigations
are available on that CPU.

There are also a pair of warning fixes, and closure of a covert
channel that pops up when protection keys are disabled.

Summary:
- Mark all Skylake CPUs as vulnerable to GDS
- Fix PKRU covert channel
- Fix -Wmissing-variable-declarations warning for ia32_xyz_class
- Fix kernel-doc annotation warning"

x86/audit: Fix -Wmissing-variable-declarations warning for ia32_xyz_class

x86/audit: Fix -Wmissing-variable-declarations warning for ia32_xyz_class

When building x86 defconfig with Clang-18 I get the following warnings:

| arch/x86/ia32/audit.c:6:10: warning: no previous extern declaration for non-static variable 'ia32_dir_class' [-Wmissing-variable-declarations]
| 6 | unsigned ia32_dir_class[] = {
| arch/x86/ia32/audit.c:11:10: warning: no previous extern declaration for non-static variable 'ia32_chattr_class' [-Wmissing-variable-declarations]

| arch/x86/ia32/audit.c:16:10: warning: no previous extern declaration for non-static variable 'ia32_write_class' [-Wmissing-variable-declarations]
| 16 | unsigned ia32_write_class[] = {
| arch/x86/ia32/audit.c:21:10: warning: no previous extern declaration for non-static variable 'ia32_read_class' [-Wmissing-variable-declarations]
| 21 | unsigned ia32_read_class[] = {
| arch/x86/ia32/audit.c:26:10: warning: no previous extern declaration for non-static variable 'ia32_signal_class' [-Wmissing-variable-declarations]
| 26 | unsigned ia32_signal_class[] = {

These warnings occur due to their respective extern declarations being
scoped inside of audit_classes_init as well as only being enabled with
`CONFIG_IA32_EMULATION=y`:

| static int __init audit_classes_init(void)
| {
| #ifdef CONFIG_IA32_EMULATION
| extern __u32 ia32_dir_class[];
| extern __u32 ia32_write_class[];
| extern __u32 ia32_read_class[];
| extern __u32 ia32_chattr_class[];
| audit_register_class(AUDIT_CLASS_WRITE_32, ia32_write_class);
| audit_register_class(AUDIT_CLASS_READ_32, ia32_read_class);
| audit_register_class(AUDIT_CLASS_DIR_WRITE_32, ia32_dir_class);
| audit_register_class(AUDIT_CLASS_CHATTR_32, ia32_chattr_class);
| #endif
| audit_register_class(AUDIT_CLASS_WRITE, write_class);
| audit_register_class(AUDIT_CLASS_READ, read_class);
| audit_register_class(AUDIT_CLASS_DIR_WRITE, dir_class);
| audit_register_class(AUDIT_CLASS_CHATTR, chattr_class);
| return 0;
| }

Lift the extern declarations to their own header and resolve scoping
issues (and thus fix the warnings).

Moreover, change __u32 to unsigned so that we match the definitions:

| unsigned ia32_dir_class[] = {
| #include <asm-generic/audit_dir_write.h>
| ~0U
| };
|
| unsigned ia32_chattr_class[] = {
| #include <asm-generic/audit_change_attr.h>
| ~0U
| };
| ...
